If the spark plug appears to be dirty, clean it with a wire brush and a bit of gasoline. If the plug is damaged or excessively worn, it’s best to replace it with a new one. Additionally, ensure that the spark plug gap is set to the manufacturer’s specifications, as an incorrect gap can lead to poor engine performance. By examining and maintaining the spark plug, you can address one of the common culprits behind a Craftsman lawn mower that runs briefly and then stalls.
Evaluating The Carburetor
After checking the fuel system and air filter, the next step in diagnosing a Craftsman lawn mower that runs for a while then dies is to evaluate the carburetor. The carburetor is responsible for creating the air-fuel mixture that powers the engine. Over time, it can become clogged with debris or gasoline residue, causing fuel flow issues and poor engine performance.
To evaluate the carburetor, start by removing it from the mower and inspecting it for any physical damage or signs of wear. Clean the carburetor thoroughly with a carburetor cleaner and compressed air to remove any built-up gunk or debris. Pay special attention to the small passages and jets within the carburetor, as these can easily get clogged and affect fuel flow. Additionally, check the carburetor gasket and needle valve for any signs of wear or damage, as these can also contribute to fuel delivery problems.
Once the carburetor has been cleaned and inspected, reassemble it and reinstall it on the lawn mower. After that, start the engine and observe how it runs. If the mower still runs for a while and then dies, further troubleshooting may be necessary. If the issue persists, it may be time to seek professional help or consider replacing the carburetor altogether.
Verifying The Ignition System
When troubleshooting a Craftsman lawn mower that runs for a while then dies, it’s crucial to verify the ignition system to rule out potential issues. Start by checking the spark plug for carbon buildup, wear, or damage. A worn-out spark plug can cause intermittent running and stalling.
